Use synthetic engine oil that meets Volkswagen Group specifications for your A4’s exact engine and year. For most modern A4s, that means an oil that meets VW 504 00/507 00 (long‑life) with a low‑viscosity grade such as 0W-20 or 5W-30; always confirm with your owner’s manual or dealer.
Identify the right oil for your specific A4
The correct oil depends on your engine code, model year, and climate. The following steps help you verify the exact specification your car requires.
- Find your engine code and model year in the owner’s manual, on the maintenance booklet, or via the vehicle’s information display.
- Check the owner’s manual or a label under the hood for the exact oil specification (for example VW 504 00/507 00 or another VW Group spec).
- Inspect the oil filler cap or a service sticker for the recommended viscosity (common options include 0W-20 or 5W-30, but this varies by engine).
- If you’re unsure, contact a dealership or a qualified independent shop with your VIN to confirm the required spec and viscosity.
By verifying the exact specification for your engine, you ensure compatibility, performance, and warranty protection.
Common specifications and viscosities used in Audi A4 engines
These guidelines reflect what many contemporary Audi A4 engines use, but there are exceptions. Always rely on the official specification printed for your vehicle.
- VW 504 00 / 507 00 (long‑life oils) with low‑viscosity grades such as 0W‑20, 0W‑30, or 5W‑30 depending on the engine and climate.
- Older or specific non‑turbo engines may call for VW 502 00 / 503.00 family oils, typically in viscosities like 5W‑30 or 5W‑40.
- Some diesel variants or market‑specific applications may emphasize 507 00 (long‑life) with 5W‑30 or 0W‑30 grades.
Bottom line: the exact spec and viscosity are engine‑ and year‑dependent. Use only oils that explicitly meet your vehicle’s VW/Audi specification to maintain performance and warranty coverage.
Recommended brands and how to choose
Choose synthetic oils from reputable brands that clearly state compatibility with VW 504 00/507 00 (or the exact spec for your engine). Look for packaging that lists the VW specification and the viscosity you’ve confirmed for your car. Popular options include Castrol, Mobil 1, Shell, Total, and Motul, among others, with products marketed for VW/Audi use.
Maintenance and oil-change considerations
Adhere to the service interval recommended by Audi, which may be displayed as a maintenance reminder (ASSYST) or printed in the owner’s manual. In normal driving, many modern A4s use long‑life synthetic oil that can span 10,000–15,000 miles (or more) between changes, but severe conditions—short trips, extreme temperatures, towing, or frequent idling—may require shorter intervals (often around 5,000–7,500 miles or annually, whichever comes first).
Always perform an oil change with the engine warmed up, use a proper new oil filter, and ensure the drain plug and oil filter are torqued to the manufacturer’s specification. If you’re changing the oil yourself, dispose of used oil responsibly at an authorized collection point.
Summary
Choosing the right oil for your Audi A4 hinges on identifying the exact engine and year and then selecting a synthetic oil that meets VW/Audi specifications (most modern A4s require VW 504 00/507 00, often with 0W‑20 or 5W‑30). Verify the specification in your owner’s manual or with a dealer, and follow the recommended oil change intervals for your driving conditions. Using the correct oil helps maintain engine performance, efficiency, and warranty protection.
